When I use ME23N to check purchase order history, I can't see Amount, Amount in local currency and currency columns in purchase order history. Then I try to change layout, but still can't find these three columns in column set or displayed columns. I have checked ME23N belongs to three roles which assigned to me. For another person who also has these three roles same as me, he can see amount , amount in local currency and currency. Then I change my parameters by SU3 same as this person. But I still can't see three columns. Please help me!
